Well what do you expect at the big prize. Here Here the price performance ratio absolutely. The performance is just as minimal as the price. I wanted to use the sled to DFF Sorry, there was the not at all. This setting is only very roughly and zimlich inaccurate. At a depth of 0.5-1mm that benefits times überhaut nothing. In addition, if you want to make the camera a little obliquely the carriage is adopted immediately (the camera slides down). The one can only counteract by fixed attracts the small set screw, but that makes the precise setting of the sharpness level impossible. I am now but decided to Einstellschlitten from Novoflex, even if it is much more expensive but he also appeared what.
Conclusion: Let it alone and prefer to give some extra money for a decent tool from. Quality costs hald!
